Anthropic and AWS enforce single-Region Claude Code in London
London-only data residency now possible for Claude Code on Amazon Bedrock
Anthropic and AWS have enabled single-Region Claude Code inference in London (eu-west-2) on Amazon Bedrock, addressing strict data residency requirements for a global organization. The solution offers two technical paths: the classic Amazon Bedrock Invoke API with an application inference profile and IAM Region conditions, or Anthropic’s Mantle endpoint with native single-Region routing.
The choice depends on the target AWS Region and model availability. For London (eu-west-2), only the classic Bedrock path works with models like Claude Opus 4.6 and Sonnet 4.6, as Mantle lacks in-Region routing there. For other Regions (e.g., Ireland, Stockholm, Tokyo), Mantle’s native AWS_REGION-based routing is simpler. Compliance is enforced via IAM policies and verified in AWS CloudTrail. Both paths require specific IAM permissions and Claude Code v2.1.94+.
